Macroeconomics and Indian Economy
Why This Chapter Matters
Macroeconomics understanding is essential for banking exams, finance interviews, business analysis, and policy understanding. These concepts explain how the whole economy functions and why prices, jobs, and growth change.
Core Concepts
1. National Income Accounting
GDP (Gross Domestic Product): Total market value of all goods and services produced within a country in a year.
Nominal GDP: at current prices. Real GDP: adjusted for inflation (better for comparison).
GDP growth rate = (Current year GDP - Previous year GDP) / Previous year GDP × 100
GNP (Gross National Product): GDP + income earned by citizens abroad - income earned by foreigners in India.
GNP = GDP + Net Factor Income from Abroad
NDP = GDP - Depreciation | NNP = GNP - Depreciation
National Income = NNP at Factor Cost
Measurement methods:
Expenditure method: GDP = C + I + G + (X-M) [Consumption+Investment+Government+Net exports]
Income method: sum of all incomes
Production/Output method: sum of value added
2. Inflation
Rise in general price level over time.
CPI (Consumer Price Index): Measures inflation from consumer's perspective. RBI's official target measure.
WPI (Wholesale Price Index): Measures at wholesale level (producer prices).
RBI's inflation target: 4% (+/-2%), i.e., 2%-6% band. Set by Government, managed by RBI.
Types:
Demand-pull: too much money chasing too few goods (AD > AS).
Cost-push: rising production costs push prices up (oil price shock, wage rise).
Built-in: wage-price spiral.
Effects: Bad for savers, debtors benefit (debt value falls), fixed income people suffer most.
Hyperinflation: Extreme inflation (>50%/month). Historical: Weimar Germany, Zimbabwe.
3. Monetary Policy (RBI)
Tools to control money supply and inflation:
Repo rate: Rate at which RBI lends to commercial banks. ↑Repo → banks borrow less → credit contracts → inflation falls. Key inflation-fighting tool.
Reverse Repo: Rate RBI borrows from banks. Always below repo.
CRR (Cash Reserve Ratio): % of deposits banks keep with RBI. ↑CRR → less money to lend.
SLR (Statutory Liquidity Ratio): % of deposits in government securities/gold/cash. ↑SLR → less to lend.
Open Market Operations (OMO): RBI buys/sells government securities. Buy → money supply increases.
Quantitative Easing: Central bank creates money to buy assets (used in crises).
4. Fiscal Policy (Government)
Government's use of taxation and expenditure to influence economy.
Expansionary: ↑Spending + ↓Tax → stimulate economy (during recession).
Contractionary: ↓Spending + ↑Tax → cool inflation.
Budget components:
Revenue receipts: taxes (income tax, GST, customs) + non-tax (dividends from PSUs, fees).
Capital receipts: borrowings, disinvestment proceeds.
Revenue expenditure: salaries, subsidies, interest payments (recurring).
Capital expenditure: infrastructure, asset creation (long-term).
Key deficits:
Fiscal Deficit = Total Expenditure - (Revenue + Non-debt Capital Receipts) = Government borrowing requirement.
Revenue Deficit = Revenue Expenditure - Revenue Receipts (if positive, govt spending more on running costs than income).
Primary Deficit = Fiscal Deficit - Interest Payments.
5. Balance of Payments (BoP)
Record of all economic transactions between India and rest of world.
Current Account: trade in goods, services, income, transfers.
Current Account Deficit (CAD): imports > exports (India typically runs CAD).
Capital Account: investment flows (FDI, FPI, loans).
BoP = Current Account + Capital Account (must balance).
Forex Reserves: RBI's holdings of foreign currencies. Higher = more stability.
India's forex reserves: among top 5 globally (~600 billion USD in 2023).
6. Economic Concepts
Opportunity cost: Cost of the next best alternative foregone.
Comparative advantage: Produce what you're relatively better at (basis of international trade).
Economies of scale: Cost per unit falls as production increases.
Market failures: Externalities, public goods, information asymmetry, monopoly.
Multiplier effect: Initial spending creates more than one rupee of total economic activity.
